Retrofit Drive Units

Preventing equipment breakdowns and extending machinery lifecycles is crucial to the success and productivity of Australia’s biggest industries.

We understand how important it is to get you back on track. In partnership with DBS Manufacturing, we source industrial plant drive units that are direct bolt-in replacements for equipment produced by a wide range of manufacturing companies. Custom engineered retrofit drive units are also available, so you can be confident that you have the right solution for every application.

Retrofit drive units are a cost-effective solution to renovating or upgrading machinery. They are easily installed and “bolt right in so you can get back to work right away.
